BS EN ISO 23900-2:2018 specifies a method of determining the colouristic properties of a test pigment
relative to a standard, and the ease of dispersion DHPVC-P of pigments from the differences in colour
strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride
(PVC-P) compounds.
The method is appropriate for use with organic and inorganic black and colour pigments and for pigment
preparations.
The ease of dispersion determined in this way is valid only for the dispersion equipment, dispersion
conditions and dispersion medium being used. The use of test conditions differing from those specified
may give different results; this applies both to the absolute magnitude and to the relation between values
of the ease of dispersion of various pigments. The subscript DHPVC-P is therefore used to designate the
value obtained as specified in this part of ISO 23900.
The principle of this part of ISO 23900 may also be used for routine quality control purposes by reference
to the photometric data generated from the sheets milled at 130 °C. For quality control purposes, the ratio
of pigment to TiO2 may be agreed between the interested parties. Ratios of 1:10 for organic pigments
and 0,2 to 0,5:1 for inorganic pigments are suggested as convenient and widely used standard ratios.
